LIDAR - Light Detection and Ranging, developed in the 1960's. Utilises light from a pulsed laser to measure vertical height of the earth's surface to generate a precise high definition 3D image of the land surface characteristics. The laser scanner is usually carried in an aeroplane and the information is collated with GPS information. The data was made freely available to all in 2015 and is enabling the discovery of numerous previously unknown archaeological sites.

Image generated using 1 metre National LIDAR Programme DTM (Digital Terrain Model) tiles from DEFRA website - environment.data.gov.uk/DefraDataDownload/?Mode=survey
The DTM tiles have digitally "removed" all vegetation and buildings which are present on the DSM (Digital Surface Model) tiles to give better visualisation of the landscape.
Data then processed using free to download Relief Visualization Toolbox (RVT) software - iaps.zrc-sazu.si/en/rvt#v
Although this may initially look daunting the downloading and processing of images is actually pretty straightforward and the DEFRA files cover the whole of England. You can generate your own location specific LIDAR maps!
